clawbot	7f472c40e2	Rule files, and bans for a clear sign of attack (closes #24) ... Every *.rules file in SWWAF_RULES_DIR is read at start and on each change, and each request is checked against the rules after the rate limits: log notes a match, block refuses with 403, ban refuses and bans the netblock for SWWAF_ATTACK_BAN_DURATION, made permanent by its next request or clear sign of attack. path, query and uri are matched as the request line sent them. bans.json gains each ban's cause, and ban notes count earlier bans by cause. The image ships 00-default.rules. Judgement call: a header sent twice is matched with its values joined by ", ". Judgement call: SWWAF_MAX_BAN_DURATION does not cap a ban for an attack. Not in this unit: offences for rule matches, with the error burst. Model: opus-5-5	2026-10-06 14:33:26 +00:00
clawbot	6ec52e5b87	Take in an admin's edits of the state files while running (closes #68) ... smallwebwaf watches SWWAF_STATE_DIR with fsnotify and takes in a saved edit of a state file in place of what it held. It knows its own writes by the SHA-256 of what it last read or wrote; each write first takes in an edit made since. An edit that does not parse is renamed to <name>.bad at the next write. Each edit taken in or set aside is logged and counted. Every ban on a netblock is checked, and the next ban is worked out from the one that ended last. README.md says how to add and lift a ban. Judgement call: a broken edit is set aside at the next write, since an editor's file can be read half written. Model: opus-5-5	2026-10-06 14:18:13 +02:00
clawbot	df2c5042d2	Keep the bans, the clients and GeoJS's answers in state files (closes #17) ... smallwebwaf now copies its state to bans.json, clients.json and lookups.json in SWWAF_STATE_DIR, as "Persistent state" in SPEC.md describes, and reads them back at start, so a restart lifts no ban and gives no client a fresh allowance. Each client gains a history, and a ban's notes count the netblock's requests. bans.json is written SWWAF_STATE_WRITE_DELAY after a ban, and every file every SWWAF_STATE_COUNTER_INTERVAL and at the stop. A ban read back is masked to its netblock and refuses every client in it. A file that does not parse, an unknown version, an entry without a field it needs, or an unwritable directory stops the start. Deviation: no AS number or name, and no ban cause, reason or lifting yet. Model: opus-5-5	2026-10-06 08:31:52 +02:00
